Adler Trumpf

Adler Trumpf was a small family-car range made by the Frankfurt-based German automobile manufacturer Adler during the 1930s. It was introduced in March 1932, with volume production beginning toward the end of that summer. The model was one of two similarly sized Adler cars introduced in 1932: the conventionally configured rear-wheel-drive Primus and the more technically progressive, front-wheel-drive Trumpf. The Trumpf therefore occupied an important role in Adler’s effort to offer a modern compact car while retaining a competitive position in a fragmented German passenger-car market. The design was associated with engineer Hans Gustav Röhr. Its principal engineering distinction was a front-wheel-drive layout, at a time when rear-wheel drive remained the dominant arrangement among mainstream German manufacturers. The 1,504 cc four-cylinder engine was mounted with its orientation reversed compared with the related Primus, placing the gearbox behind the front axle. The car also used independent suspension, contributing to its advanced technical character. A four-speed manual gearbox was fitted, although it lacked synchromesh; gear selection was operated through a column-mounted lever rather than the floor lever used in the rear-wheel-drive Primus. At launch, the Trumpf was offered as a two-door Limousine sedan and as a cabriolet. The all-steel bodies were supplied by Ambi-Budd of Berlin. The original engine was rated at 32 PS and gave the car a claimed top speed of 95 km/h. In 1933, Adler expanded the range with an optional 1,645 cc engine producing a claimed 38 PS and a top speed of 100 km/h. The body program also became more extensive. A newer steel body with a more steeply angled windscreen and rear-hinged front doors was introduced, followed by two- and four-door sedans, cabriolets, and an open Sport two-seater. Ambi-Budd-bodied sedans built from 1934 to 1936 were commonly identified as Jupiter-bodied cars. The original Trumpf remained available with the 1,504 cc engine until 1934 and with the 1,645 cc engine until May 1936. Approximately 18,600 examples were produced during this period. Together with the smaller Trumpf Junior, the model helped Adler maintain a high position in German passenger-car sales, generally around third or fourth place between 1932 and 1936. Its estimated market share during the original production period was approximately 3% to 4%, although the contemporary German market was considerably more fragmented than the later mass market. In May 1936, the 1.7-litre version was replaced by the longer and more streamlined Trumpf 1.7 EV, also referred to in contemporary model descriptions as the Trumpf 1.7 E. It retained the 1,645 cc engine and claimed 38 PS, but used a longer wheelbase, a longer body, a six-light four-door sedan design, and a more extended rear overhang. The standard sedan bodies continued to be supplied by Ambi-Budd, while Karmann of Osnabrück supplied standard cabriolet bodies. Claimed top speed rose to 102 km/h. Adler produced 7,003 examples of the 1.7 E in just under two years, representing slightly less than 2% of the German passenger-car market during that period. The Trumpf range was discontinued as Adler’s passenger-car business weakened before the Second World War. Adler’s market position fell to fifth place in 1938, while Ford’s German output increased substantially. The name is consequently associated with a historic Adler vehicle family rather than with an independent contemporary automobile company or an active modern brand.

Adler introduced the Trumpf in March 1932 as part of a two-model expansion into the smaller family-car segment. The second of the two cars to reach volume production, it entered series manufacture in late summer 1932. The related Primus used rear-wheel drive, whereas the Trumpf adopted front-wheel drive and independent suspension. This gave Adler a modern technical alternative in a market still dominated by more conventional layouts. The Trumpf used a 1,504 cc four-cylinder engine producing a claimed 32 PS. Its engine and gearbox arrangement differed from the Primus: the engine was turned around and the transmission was positioned behind the front axle to drive the front wheels. A four-speed unsynchronised manual transmission was operated through a column-mounted control. The original body range consisted of a two-door Limousine sedan and a cabriolet, both using Ambi-Budd all-steel bodies. For 1933, Adler added a 1,645 cc engine rated at 38 PS and introduced a revised body with a more modern windscreen and rear-hinged front doors. The car became available in two- and four-door sedan forms, as well as cabriolet and open Sport two-seater configurations. From 1934 through 1936, Ambi-Budd sedan bodies were known as Jupiter-bodied cars. The 1,504 cc version ended in 1934, while the 1,645 cc Trumpf continued until May 1936. The original Trumpf generated approximately 18,600 units. With the smaller Trumpf Junior, it helped Adler remain among Germany’s leading passenger-car manufacturers in the mid-1930s. In May 1936, Adler replaced it with the Trumpf 1.7 EV, also described as the 1.7 E. This derivative retained the 1,645 cc engine but used a substantially longer wheelbase and body, a streamlined four-door six-light sedan body, and a claimed top speed of 102 km/h. Karmann supplied the standard cabriolet bodies for the newer version. Adler built 7,003 Trumpf 1.7 E cars in less than two years. By 1938, however, Adler had fallen to fifth place in the German market, while Ford was expanding rapidly. The Trumpf line was subsequently discontinued as Adler’s passenger-car activity declined. Its historical importance rests on its early front-wheel-drive architecture, its association with Hans Gustav Röhr, and its contribution to Adler’s prewar passenger-car range.

  The original Trumpf was a front-wheel-drive small family car introduced in 1932. It used a 1,504 cc four-cylinder engine rated at a claimed 32 PS and was initially offered as a two-door Limousine sedan and a cabriolet. Its independent suspension, front-mounted drivetrain, column-shifted four-speed gearbox, and Ambi-Budd steel bodies distinguished it from Adler’s rear-wheel-drive Primus.

  The 1.7-litre Trumpf used the larger 1,645 cc four-cylinder engine introduced as an option in 1933. The engine was rated at a claimed 38 PS and gave a stated top speed of 100 km/h. The version was offered with several body styles, including sedan, cabriolet, and open two-seat Sport bodies, and remained in the range until its replacement in May 1936.

  The Trumpf 1.7 EV, also called the 1.7 E in contemporary descriptions, was the 1936 successor to the earlier 1.7-litre model. It retained the 1,645 cc, 38 PS engine but gained a longer wheelbase, a longer and more streamlined body, and a four-door six-light sedan configuration. Ambi-Budd supplied sedan bodies and Karmann supplied standard cabriolet bodies. Its claimed top speed was 102 km/h.
